Viking colonists? JUL 25 2011

So, the study looked at 14 Viking burials from the era, definable by the Norse grave goods found with them and isotopes found in their bones that reveal their birthplace. The bones were sorted for telltale osteological signs of which gender they belonged to, rather than assuming that burial with a sword or knife denoted a male burial.

Overall, McLeod reports that six of the 14 burials were of women, seven were men, and one was indeterminable. Warlike grave goods may have misled earlier researchers about the gender of Viking invaders, the study suggests. At a mass burial site called Repton Woods, "(d)espite the remains of three swords being recovered from the site, all three burials that could be sexed osteologically were thought to be female, including one with a sword and shield," says the study.
